Stable small overclock for 6600K?

I have an i5 6600K and a Z170 Pro Gaming motherboard and when it comes to overclocking, I'm a newb. 

 

The only values I've changed relating to overclocking is the multiplier and XMP. I've set the multiplier to x42 and turned XMP on (to make the RAM sticks run at its 3000 MHz rated speed.

 

Everything else is stock/auto.

Change the voltage to fixed. Never, EVER use Auto voltages when OCing.

 

Something around the 1.25~1.3v range should do, depending on your chip and cooling.

with anything above 4.4 I'd understand but 4.2? That's hardly an overclock.

As@Imakuni stated, never use automatic voltages as it almost always sets values much higher than is actually needed. 

I see. So something around 1.246 "should" work? What about LLC?

Honestly, even at stock you shouldn't leave the voltage on auto. Regardless, any OC is an OC, even if it's a small one.

Through trial and error, fiddle with your voltage and LLC settings to achieve your desired voltage. For example, I use 1.275v, which get's shot up to 1.296v once LLC kicks in.

 

See what works best for you.

But if it works, then it works? Right? Because I have no temp issues or BSOD's related to the OC in any way. It idles around 26-27c with my H100i V2. Honestly, I just want a small, easy overclock without unnecessary fiddling. That's why I left it at x42 instead of going over that.

 

If we put it like this: What issues could theoretically arise by leaving most/all settings on auto? I know that auto on boards back in the day was bad but it really doesn't set that high a voltage for me with this board. It's usually around 1.246V. 

 

Check this screenshot I grabbed in AI Suite 3 (I do NOT use AI Suite 3 to change overclock settings!!)

With auto, nothing prevents the voltage from spiking up, adding unnecessary power consumption and heat. Or dropping in a bad moment and causing instability when you least want it.

 

Since you've said it usually hovers on ~1.25 with no problems, just set it to that and call it a day. At worst, you are going to find out your chip is unstable at that, at which point it would be pretty easy to just bump it up a notch and call it a day again (rinse and repeat as necessary).

What about LLC and SVID?

Leave LLC as is for now. IF you can't get to the correct voltage, THEN try to set it up.

 

No need to mess with SVID.

To whatever the board deems necessary. See, you are already at 1.312v, even with a rather weak stress test.

Yeah you're right.

 

But if it reports 1.3 as max, shouldn't that be max?

5ghz should be easy and a small OC.

You got it wrong. That "max" doesn't stand for "maximum possible voltage". It stands for "maximum voltage that was registered in real time".

 

As I said, nothing prevents the board from saying "oh, I think you nee 1.4v right now". And if that happens, that "max" is going to change to 1.4v

I consider 5ghz to be quite hefty, lol. ?

Ehh it's only 1000mhz OC, my X5650 went from 2.65 to 4.5 :P

 

It can probs do more but i'm pushing the limit's of my motherboard.

Oh I didn't consider that.

What is SVID even? LLC if I understand correctly adjusts the vcore during load to batle vdroop?

 

LLC is also on auto but I guess set the vcore to 1.264 or thereabouts and LLC level 1, 2 or 3?

LLC depends on the Bios. Mine allows Auto and 1~4. I use it at 3; 4 causes droop, 2 and above raise the voltage too much. Again, find what works best for you.

What works best for me is x42 multiplier (and XMP on the RAM) and having everything else on auto/stock... :P 

 

No BSODs or crashes.

If I set the voltage to manual, will the cpu always receive that voltage even if the frequency drops? If so, would it be worth it to try adaptive or offset?

If the C-states kick in, they'll still allow voltage to drop.

All that is enabled by defualt so I guess they'll kick in at some point?

 

Would you recommend manual mode over offset/adaptive? 

I use Manual (though mine is on 100% load 24/7, so it doesn't really matter...).

Wouldn't really matter much for me either, this is a gaming rig and not a power-saving Chromebook, lol. Besides, electricity is cheap.

 

What would you recommend I'd do? Set manual vcore around 1.25v and leave everything else?
